This release has been tracked through the 0.12.0 project.

Highlights for cloud-hypervisor version 0.12.0 include:

ARM64 enhancements

The use of --watchdog is now fully supported as is the ability to reboot the VM from within the guest when running Cloud Hypervisor on an ARM64 system.

Removal of vhost-user-net and vhost-user-block self spawning

In order to use vhost-user-net or vhost-user-block backends the user is now responsible for starting the backend and providing the socket for the VMM to use. This functionality was deprecated in the last release and how now been removed.

Migration of vhost-user-fs backend

The vhost-user-fs backend is no longer included in Cloud Hypervisor and it is instead hosted in it’s own repository

Enhanced “info” API

The HTTP API endpoint has been extended to include the details of the devices used by the VM including any VFIO devices used.
